Question Sparkplug/cable problem- 2000RS

Let's see if I can explain what happened, and you can make suggestions:

I drove my car up to Vermont Wednesday night (about 120 miles) and it was running just fine. I started it up again thie morning (saturday) to warm it up, and it was running REAL rough, like rocking back and forth rough, and the CEL was blinking.

I popped the hood, and where the spark plug cable #1 was connected to the distributor block, it was sparking, maybe 3-5 sparks a second. I figure it must just be loose, so I stop the car, take the cable off, blow dust out, squeeze it a little to make it fit tighter, and pop it back on. Restart the car again, and it's still sparking, but less than before. Maybe 2-3 times a second. I do the same thing again, and this time, only 1 time a second or so.

I figure this should be good enough to get me to someplace I can have it looked at. I start out, and the car definitely isn't it's normal self- feels less peppy, shifts rougher, etc.

About 10 minutes later, I pull over and pop the hood, and no sparks- the car also seems to have returned to it's normal self.
But the CEL is still on.

So:
A) Any clue what happened?
B) Is it serious?
C) How quickly should I rush to a dealer to have it looked at?

Thanks for any help- either respond here or e-mail me at fuzzbox@world.std.com

How many miles are on your RS? Did you check the #1 spark plug wire boot for cracks? A new #1 spark plug wire is only $11 or so (Part #22451AA720).

Fuzzbox,

IMHO I'd get those ignition wires replaced, as a set even though only one has probably failed.

Certain serious CE fault codes, such as misfires in your case (I believe), will annunciate by blinking first and then remain lit (latched) even after the source of the fault had been corrected, until a reset is made. For minor fault codes, the CE will light up, without ever blinking the CE light will extinguish as soon the source of the fault is corrected.

never replace just one wire...replace them as a set...you could replace one and 2 weeks late 1 or 2 more go bad.

what jeremy said, replace yoru wires, before the problem returns, scoobies are known for bad wires.

I say it again, dont drive when the cel is flashing, it flashes because of a misfire with lack of spark, meaning that cylinder has no spark, so the raw fuel is not being burned yet dumped into the cats, cats and fuel dont mix...and you could burn them up if you drive for to long. Im sure your fine, just change the wires.

oh and on obd2 vehicles in order for your cel to go out by itself, the car has to run through IIRC 2 complete drive cycles...and that can take a long time! to much to explain, change the wires, and reset the ecu and youll be fine.

Ok, guys Thanks. I figured it must just be a failed wire as well.

Unfortunately, nobody is open on Sundays here, so I'll just have to wait until monday and take it in.

I just turned over 36,000 miles this trip. Is it usual for wires to only last that long?

So I took it to the dealer today, but it was too late to do anything, but he'll get it tommorow morning, but he popped the hood and said that he thinks I need both the Spark plug cables AND a new coil pack (the thing I caled the distributor block).

Does that sound right to any of you? What would have happened to the coil pack?

Is your car still under warranty????????? if so ,let em replace both.If not id question th coil pack replacement.The techs here would know better then me,but a coil pack at 36000 miles seems abit much.Was it the coil pack that caused the wires to go ,somewhat prematurely???Ill bet a coil pack is pricey.
My two cents

The ignition coil pack is around $130.

I AGREE!!! It's the plug wires. Same thing happened to my 99 RS but on #4. Dealer replaced the plugs and coil pack but the symptoms returned after about a month. So I replaced the plug wires and the problem hasn't returned since (nearly a year now).

well if the spark was arching towards the coil pack then it has done damage to the coil pack and if he ptus new wires on the coil pack will fail shortly there after and your car most likely won't even run after that. and it's a coil pack/ignition control module all in one piece.

Well, they replaced the coil pack under warranty, but only replaced wire #1, and charged me for it. When i asked the Manager about it, he said that they checked all 4 wires, and #1 was the only one that was bad.

Of course, they charged me almost $70 for the wire and labor for the wire and pack. Grr.

Should I have insisted on them replacing all 4 anyways? Or should I just invest in a better set of wires, and replace all 4 myself, knowing that the Coil pack is good?

...so many questions...

Get them to change the other three wires. If they refuse, then you will have to invest some money in the three remaining wires yourself. Unless you plan to switch to an aftermarket set of wires or your new #1 wire is defective, there is no need to buy the #1 wire again.

seeing as how you paid for the wire(which i am confused about) i would just put them on yourself...get a set of NGk's or something along those lines. You should just do them yourself.
